American standard turbine transmission ball valve Q341F

American standard turbine transmission ball valve Q341F

The Q347F manual turbine fixed ball valve is a new generation high-performance ball valve suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in the design. Fixed ball valves are suitable for various corrosive and non corrosive media. Compared with floating ball valves, fixed ball valves transmit all the force generated by the fluid pressure in front of the valve on the ball to the bearing during operation, which does not cause the ball to move towards the valve seat. Therefore, the valve seat will not bear excessive pressure. Therefore, fixed ball valves have smaller torque, smaller valve seat deformation, stable sealing performance, and longer service life, making them suitable for high-pressure and large-diameter applications.
Advanced spring pre seat components with self tightening characteristics achieve upstream sealing. Each valve has two valve seats, which can seal in each direction, so there is no flow restriction during installation, and it is bi-directional. Fixed ball valves are generally installed horizontally.

2、 Working principle of Q347F manual turbine fixed ball valve:
Q347F manual turbine fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in the design, and it is suitable for various corrosive and non corrosive media. Compared with floating ball valves, during operation, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, which will not cause the ball to move towards the valve seat, so the valve seat will not bear excessive pressure. Therefore, fixed ball valves have smaller torque, smaller valve seat deformation, stable sealing performance, and longer service life, making them suitable for high-pressure and large-diameter applications. Advanced spring pre seat components with self tightening characteristics achieve upstream sealing. Each valve has two valve seats, which can seal in each direction, so there is no flow restriction during installation, and it is bi-directional. This valve has two types of valve body structures: two-piece and three piece. The middle flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring. There is no spring at the back of the steel ring to ensure that the valve seat is tightly attached to the ball, maintaining a seal. There are no PTFE bearings on both the upper and lower valve stems, reducing wear and making operation effortless. There are no adjustment plates at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Full bore: The valve flow aperture is consistent with the inner diameter of the pipeline for pipeline cleaning. Applicable media: water, gas, oil, natural gas, and acid-base corrosive media.

3、 Q347F Manual Turbine Fixed Ball Valve Product Features:
1. Long service life, the sealing ring is made of self-lubricating polytetrafluoroethylene material. The sphere and sealing ring are slightly worn, effectively improving their service life;
2. Small size, light weight, easy to install and maintain;
3. The fixed ball valve structure can be installed in any direction and at any part of the pipeline;
4. V-shaped overlapping axial packing, achieving anti-corrosion A-level sealing.

【Overview of American standard fixed ball valves】

American standard fixed ball valveIn the mining, refining, processing, and pipeline transportation systems of oil, natural gas, coal, and ores; In the production of chemical products, pharmaceuticals, and food; In the power production systems of hydropower, thermal power, and nuclear power; In the water supply and drainage, heating, and gas supply systems of cities and industrial enterprises; In the irrigation and drainage system of farmland; Widely used in the metallurgical production system, it is an important mechanical product closely related to production construction, national defense construction, and people's lives. Ball valves are used in various pipeline systems to cut off or connect the flow of media, so that the media is transported to designated points according to predetermined procedures.

【Operation and use of American standard fixed ball valves】

1) Before operation, it is necessary to confirm that the pipelines and valves have been flushed.

2) When the direction indicator arrow of the actuator is parallel to the pipeline, the valve is in the open state; When the arrow is perpendicular to the pipeline, the valve is in the closed state.

3） All types of manual ball valves installed on insulated pipelines must not have handles facing downwards.

4） The installation position, height, and import/export direction must meet the design requirements, and the connection should be firm and tight.
